Century Dictionary and Cyclopedia

1. n. In Rom, mythology, the queen of heaven, the highest divinity of the Latin races in Italy next to Jupiter, of whom she was the sister and the wife. She was the parallel of the Greek Hera, with whom in later times she became to a considerable extent identified. She was regarded as the special protectress of marriage, and was the guardian of woman from birth to death. In Rome she was also the patron of the national finances, and a temple which contained the mint was erected to her, under the name of Juno Moneta, on the Capitoline. In her distinctively Italic character, Juno (called Lanu-vina, from the site at Lanuvium of her chief sanctuary, or Hospita, the Protectress) was a war-goddess, represented as clad in a mantle of goatskin, bearing a shield and an uplifted spear, and accompanied, like Athena, by a sacred serpent.
2. n. The third planetoid, discovered by Harding, at Lilienthal, in 1804.
